Abstract:
Boeremia exigua var. exigua syn. Phoma exigua var. Exigua formerly known as Ascochyta phaseolorum, one of the most devastating pathogens causing Ascochyta blight and resulting in severe yield losses in legume crops. In this study, 70 genotypes were screened against B. Exigua for development of management strategies and to identify resistant genotypes. However, neither of the genotypes was found completely resistant to this destructive disease and only 4 genotypes viz., SKUA-WMB-11, SKUA-WMB-37, SKUA-WMB-53,SKUA-WMB-77were found moderately resistant. The genotype SKUA-WMB-105 was found to exhibit maximum disease intensity (63.14%) and SKUA-WMB-11 was found to have lowest disease intensity (5.58%). These genotypes could be used as a source for disease resistance in future and in developing specific breeding procedures for crop improvement.
